`LooM-REED.

SPECIFIGATION forming part of Letters Patent No. 532340, dated January 8, 189 5.

Application filed February 2, 1894. Serial No. 4:9 8,908. (No model.)

plied in such looms, although they may be' used in other classes of looms.

In wire looms the dents must be arranged so that the warp wires are positively guided on opposite sides, and lateral play of the wires prevented, while at the same time it is important that all irregularities in the wires caused by knots, bends, the., shall not catch in the dents, as would be the case if the two guiding surfaces for the opposite sides of the wire were positioned directly opposite each other and so close together as to furnish the desired positive guide of the wire. These results are secured in accordance with the present invention by using dents having their guiding portions equal in width to the thickness between two wires, so that the opposite sides of each dent shall form guiding surfaces for two adjacent wires and making these dents tapering and placed with their thickest portions, which form the guiding surfaces, alternately at the front and rear of the reed and at a sufficient distance apart longitudinally of the warp to provide space for the easy passage of irregularities.

The form of thedents may be varied and many of the advantages resulting from the invention be Secured, but it will be found preferable to make the dents with rounded guiding surfaces which enable the reed to swing more readily over the wire and prevent the catch of the dents on knots therein, and in the Construction which I deen preferable the dents are made somewhat oval in cross section, thus tapering in both directions from the thickest or guiding portion and more gradually on one sidea Iu the accompanying d'awings forming a part of this specification, there are shown, for the purpose of illustration, constructions embodying the invention in the preferred forms, and a detailed description of the same will now-be given and the features forming the invention then specificallypointed out in the claims.

In the drawings-Figure 1 is a' side View of a portion of a reed of the prefem'ed form. Fig. 2 is an enlarged cross section of the dents. Fig. 3 is a View similar toFig. 2 showing a modification.

Referring now especially to' Figs. 1 and 2, A is the reed frame, B the dents, and C the wires. The dents B, as shown, are formed of bars approximately oval in cross section, providing rounded guidin'g portions and tapering in both directions from the thiokest or guiding portions but tapering more gradually in one direction than the other, forming a quicker taper or curved surfaces Z on shorter radii and a slower taper or ourved surfaces on longer radii and arranged alternately with their guiding portions at the front and rear of the reed. The thickness of the guiding portions is equal to the distance between adjacent wires and the opposite sides of each dent form guiding surfaces for two adjacent wires. Thus the wires, while positively guided against lateral play, have a freedom of movement between the dents to permit the passage of irregularities.

The dents may be nade of any suitabl width, that shown forming an efficient construction pernitting irregularit ies to pass readily.

It will be seen that the edges of the dents at the front side of the reed form the beating up surfaces as usual. While these heating up surfaces are wider apart than in reeds of i the commonforms, they will be found suffi-' cient.

While the Construction shown in Figs. 1 and 2 will be found very desirable as provid ,ing extended guiding sui-faces, thus lessening the efiect, of wear and increasing. the durability of the reed, it will be understood that this form may be varied without departing from the invention. Thus, in Fig. 3, I have IOO dents, but only such dents tapering from their guiding portions toward the opposite side of reed, as defined by the claims, so that any beating up surfaces at the front of the reed between said guding portions are forned on the dents themselves and not by bars separate therefrou.

What I claim is- 1. A loom reed having dents provided with guiding portions equal in thickness to the distance between adjacent warp strands, said guiding portions being placed alternately at the front and rear of the reed and said dents tapering to the opposite side of thereed, substantially as described.

2. A loom reed having dents provided with curved guiding portions equal in thickness to the distance between adjacent warp strands,

said gui din g portions being placed alternately at the front and rear of the reed and said dents tapering toward the opposite side of the reed, substantially as described.

3. A loom reed having dents oval in cross section and having their thickest or guiding portions alternately at the front and rear of the reed and equal in thickness to the distance between adjacent warp strands, the

thinner portions of said dents forming beating up surfaoes atthe opposite side of the reed from the guiding portio'ns substautally as shown and described.

In testimony Whereof I have hereunto set my hand in the presence of two subscribing witnesses.
